Review on Rupse 2ps License Plate Light - Waterproof 12V LED Bulb for Car Motorcycle Truck RV ATV Bike - License Tag Screw Bolt Lamp (Blue) by Tony Stennis

Looks good. I had no such issues with build quality. The entire body looked high quality and solid. The only problem I had on this front was that because these pieces were round, they were very difficult to tighten. The cabling strength is pretty flimsy and I wish there was some sort of quick connect built in. Even a 3.5mm mono plug will do. But in fact the wiring is more than enough. The standard thread/bolt size is 6mm. Identical to the Honda license plate bracket screw. Either way. I decided to do something irresponsible and stupid. I installed them as front lights on my Accord that connect to the parking light. It's barely bright enough for a full-size license plate, and I have a plastic plate cover that really helps diffuse the light. If this is your only source of illumination for the back of your car, you will see red and blue. A Dupont connector will not fit through a 6mm threaded hole if another wire also enters the hole.
